Abstract

L'invention concerne un procédé permettant de coder un message, qui consiste à exécuter un codage bicanal dudit message en une chaîne robuste et en une chaîne fragile; à transmettre la chaîne robuste via un canal fragile; et à transmettre la chaîne fragile via un canal robuste. Avant cette étape de codage de message bicanal en chaîne robuste et en chaîne fragile, le nombre de caractères du message peut être réduit afin de limiter la taille du message codé. Le codage bicanal consiste à créer la chaîne robuste par codage du message à l'aide d'un dictionnaire de mots de code; et à créer la chaîne fragile par codage du message à l'aide d'un algorithme de compression. La chaîne robuste peut être transmise par incorporation dans une image. La chaîne fragile peut être transmise par incorporation dans un code à barres 2D.
